Remove Personal Data from a Document
The Problem:
Last month, a colleague blew the whistle on a few corners our boss had been cutting. She anonymously dropped HR a document, but it turned out that her name was hidden in it somewhereso now she's no longer working here.
The Solution:
In each document you save, Word stores your username (as entered on the User Information tab of the Options dialog box) and other identifying information. Word 2003 and Word XP let you easily remove personal data from a document; Word 2000 does not, but you can choose File 
Properties and manually delete particular items of information.
To remove personal data from Word 2003/XP documents, choose Tools Options, click the Security tab, and check the "Remove personal information from file properties on save" box. For security, you may also want to check the "Warn before printing, saving or sending a file that contains tracked changes or comments" box so that Word prevents you from saving or sending a file that contains text that may be hidden from you.
After choosing these options, you must save the document to make the options take effect.
